Timber

Panga Panga is extraordinary in its rarity as it is only found, in commercially viable quantities, in
Mozambique. Its dark colours, with rich parenchyma bands brings a touch of the exotic to finished pieces. The heartwood is dark chocolate brown with paler broad bands. At 880kg/m3 the heartwood is extremely durable. It sandpapers well and takes varnish and oils well. It is used in furniture, turning, parquet flooring and carving.
